A plugin used to display stats from a wireless LAN interface.
xfce4-wavelan-plugin displays the following information about a WaveLAN device:
At the time of this writing NetBSD, OpenBSD, FreeBSD and Linux are supported.
The plugin shows signal quality as a percentage on Linux and as dBm on BSDs. Therefore, the progressbar will probably be not really accurate on BSDs, as dBm is hardly comparable to a maximum.
Add the plugin to the panel, and select the wireless interface you want to monitor.
